1 State Wind Power Policy: An Update on RPS, SBC, and IRP Ryan H. Wiser Lawrence Berkeley National Laboratory Wind Powering America Annual State Summit Evergreen, Colorado May 19, 2005

2 Presentation Overview Recent wind project development has largely been driven by state policy 1. Renewables portfolio standards 2. Renewable energy funds 3. Integrated resource planning 4. Other policy approaches Annual US Wind Development (MW) Other (economical, green power, etc.) RPS-related Renewable Energy Fund-related % Other 47% RPS 14% RE Fund

3 State Renewables Portfolio Standards and Purchase Mandates 19 States and D.C. NV: 15% by 2013 CA: 20% by 2010 MT: 15% by 2015 MN (Xcel): 825 MW wind by % by 2015 IA: 105 amw CO: 10% by 2015 NM: 10% by 2011 ME: 30% by 2000 WI: 2.2% by 2011 MA: 4% new by 2009 NY: 24% by 2013 RI: 16% by 2019 PA: 8% by 2020 CT: 10% by 2010 MD: 7.5% by 2019 NJ: 6.5% by 2008 DC: 11% by 2022 AZ: 1.1% by 2007 HI: 20% by 2020 TX: 2880 MW by 2009 New since Jan 1, 2004 Significant revision since Jan 1, 2004

Hawaii Maine Montana not included in tabulation

5 Non-Exhaustive Review of Recent Impacts of RPS on Wind Power Development New York Four contracts for 317 MW in NY, MD, PA, NJ California PG&E: MW from three contracts SCE: MW form three contracts SDG&E: 150 MW of new wind under contract LADWP: 120 MW approved Wisconsin 200 MW may be installed in 2005 Hawaii New Mexico 24 MW of wind under contract for construction this year 140 MW under contract to Xcel Texas Over 500 MW planned for construction in 2005 Minnesota Over 200 MW proposed for construction in 2005 Massachusetts Connecticut Substantial development activity in New England as result of MA and CT RPS

6 Significant Opportunities in Near Future High Priority Regulatory Implementation New Policy Creation High Priority (entirely new policy or revision to old) New Policy Creation Slightly Lower Priority (entirely new policy or revision to old)

7 But the Potential Impacts May Not Be Realized Unless We Get the Design Right Lack of Long Term Contracts Major problem in Northeast, where retail competition exists and where renewable energy sources are more expensive Force Majeure Clauses and Cost Caps New RPS policies increasingly including a lot of wiggle room to possibly allow escape from full compliance (e.g., MT, PA) Use of Non-Compliance Penalties Full compliance not being achieved (NV, AZ) or unlikely to be achieved (CA) in some cases will penalties be used to enforce compliance? Lenient Geographic Boundaries Wind community has often sought broad geographic scope of eligibility, but have we gone too far (e.g., PA, MD, NJ, NY) Design Complexity Will design complexity grind the CA RPS to a halt

8 State Clean Energy Funds 15 states collecting over $300 million per year for renewable energy support Majority of funding collected through a small surcharge on electric bills (SBC) Common programs for wind Financial support for large wind projects Pre-development support for large wind projects Building green power market demand Support for community wind Support for customer-sited, smaller scale wind Wind R&D

9 Financial Support for Utility-Scale Wind Has Been Provided by Eight States Obligated Incentives ($) Obligated Capacity (MW) On-Line Capacity (MW) Pending Capacity (MW) # Wind State Projects CA 25 $79,098, PA 8 $14,000, IL 4 $9,305, NY 6 $22,100, OR 1 $3,800, MN 64 $51,441, MA 2 $16,238, NJ 2 $6,300, Total: 112 $202,284,417 1, ,303 Notes: 1. Updated September 2004; some projects have come on-line since that time, e.g., California now has 348 MW on-line; others have been cancelled, e.g., 21 MW project in NJ 2. Massachusetts obligated incentives is the amount placed in escrow; nominal value of potential obligations is $25.8 million

10 Integrated Resource Planning Western IRPs are leading to significant planned wind investments, above and beyond RPS requirements Cumulative Nameplate Capacity (MW) 8,000 7,000 6,000 5,000 Aggregate Non-RPS 4,000 3,000 2,000 Aggregate RPS 1, Non-RPS: Wind accounts for 93% of new capacity in 2014 RPS: Resources often unspecified New Renewables Capacity in 2014 (MW) PG&E Pacifi- Corp SCE PSE SDG&E PSCo Idaho Power Nevada Power PGE North- Western Sierra Pacific Avista Non-RPS 0 1, RPS 2,150 NA 1,021 NA 630 NA NA 361 NA NA 137 NA Total 2,150 1,420 1,

11 Why Because Wind at $20-40/MWh Can Be Cost Effective, if the IRP Is Done Right IRP is an enormous opportunity to get wind at the table as part of a low-risk, low-cost portfolio of new resource additions A Wind Friendly Integrated Resource Plan The direct costs and benefits of wind are fairy evaluated: capital, operating, tax incentives, integration, transmission, capacity value The cost of new conventional resources is correctly evaluated, including consideration of base-case fuel prices and fuel price risks The financial risk of future environmental regulations, most importantly carbon, is considered and evaluated

12 Our Review of 12 Western IRPs Reveals a Number of Important Observations 1. Western utility resource plans have begun to consider RE as a serious resource option 2. Resource plans in RPS states, however, often fail to evaluate RE as a serious resource option, beyond the RPS 3. Some plans establish low wind-penetration limits that are capping wind additions at seemingly artificially low levels 4. Candidate resource portfolios are not always constructed and analyzed so the risk-reducing attributes of RE will shine through 5. The value of the federal production tax credit (PTC), and the risk of its expiry, are not analyzed adequately in many resource plans 6. The methods for evaluating wind s integration costs and capacity value are improving, but more work remains 7. Fuel price risks appear to be evaluated relatively well, but the risk of fuel-price increases is sometimes underestimated 8. Environmental regulatory risks are increasingly recognized (at least for carbon), but the risk is not consistently evaluated among plans

13 Exogenous Build Limits Cap the Amount of Wind Selected by Some Resource Plans % Wind Cap (MW nameplate) MW (left scale) 2500 % of Peak Load (right scale) % 20% 15% 10% 5% Wind Cap (% of Peak Load) 0 0% Idaho Power PGE PacifiCorp 2003 PSE 2003 PSE 2005 NW E PSCo Supp. PSCo Orig. Avista Sierra Pacific Nevada Power Note: caps for Nevada Power and Sierra Pacific are from 2001 renewable energy RFP; PSCO (original plan) established 500 MW cap after modeling higher levels of penetration NWE, PSE 2003, PSCo (orig.), and Avista all chose portfolios with wind at the cap (Sierra Pacific and Nevada Power do not report RE additions by technology, but presumably would also hit their low caps)

14 Seven of Twelve Western Utilities Already Consider Carbon Risk, Through Various Means Levelized $/ton CO2 (2003 $) Unweighted Scenarios Range of Scenarios Weighted Average Base-Case Assumption Avista PG&E PSCo (IRP) PSE 2005 Weighted Scenarios Idaho Power We recommend that all utilities evaluate carbon risk a greater level of consistency in evaluation approaches be sought a broad range of possible regulatory environments be considered PGE PacifiCorp 2003 Base Case with Unweighted Scenarios PacifiCorp PSCo 2004 (Settlement)

15 Other State Policies State Tax Incentives Property, sales, and income tax incentives e.g., New Mexico production tax credit: 10 years, 1 cent/kwh Posted Avoided Cost Rates With high gas prices, and low wind costs, posted avoided cost rates can spur smaller and community-owned wind projects e.g., in Idaho, long-term avoided cost rate ~$60/MWh for projects under 10 MW; two wind projects already signed on Fossil Gulch (10.5 MW) and Montana project (9 MW) Utility Profit Incentives As a part of other policies, or separate from those efforts, consider offering utilities a profit motive for aggressively pursuing renewable resources Few examples to draw upon, but Colorado and Hawaii are exploring incentives within their RPS policies Berkeley Lab and Regulatory Assistance Project collaborating on project to explore the mechanics and options for this policy approach

16 Conclusions State RPS policies are currently a principal form of support for utility-scale wind projects, and are becoming increasingly popular State renewable energy funds are unlikely to play as sizable a role, but will play a critical role in certain markets and for certain applications IRP may be the new frontier to sizable wind expansion in West and Midwest Other options to consider State tax incentives Posted avoided cost rates Utility profit motive
